The next morning, Anna picked up Gloria and said "Hey, Sandy? Remember how I said I wanted to try being a dude this week?"
"Yeah," said Sandy. "Did you want to do that today? We can turn Gloria human again and then take you to the gender store."
"Well...." said Anna, slyly. "I've been thinking about it some more and I realized I don't really want to be a man. All I really wanted to know was what it feels like to have a cock."
"Oh?" said Sandy.
"Yeah, and I was thinking we could enlist Gloria's help for that."
"You want to turn her into a penis!" exclaimed Sandy. "Let's do it!"
Sandy went and got the appropriate powder and returned. Anna was already stripped naked and held Gloria up against her clit. "Ok, do it" she said.
Sandy sprinkled the powder on Gloria and the woman-toy felt herself changing. She got softer and began to droop down. At the same time she suddenly felt 'attached' to something behind her. She realized it was Anna. She had become her penis!
Gloria began to flex, realizing she could move again. Sort of. She could somehow tell that her owner Anna was looking at her wife's breasts. The sensation caused Gloria to stretch and... grow. She felt testicles grow out from beneath her as she stood up.
"I'm getting erect!" thought Gloria to herself. "This is so cool."
"Oh, wow!" said Sandy. "You're really getting hard. I guess Gloria's having fun too!"
"Yeah, said Anna. She feels really good." Anna bit her lip and stared at Sandy, wiggling her eyebrows.
"Oh, no," said Sandy. "Don't give me that look. You are not putting that thing inside me!"
"Come on," said Anna, clearly frustrated. "Don't think of it as a dick. Think of it as our friend Gloria. You had her inside you last night."
"Yeah, as a toy!"
"And now she's a part of me. Your wife. It'll be exactly the same."
"Yeah... come on!" thought Gloria impatiently. "Let me in! I wanna get in!" She realized that she was thinking just like a dick now. My god, she had never felt this impatient about sex before! She could sense the sperm swirling around in her balls and she wanted to get it OUT of her. It was a need unlike any other she'd experienced before.
Anna felt it too. "I love you" she said as a last-ditch effort.
Sandy smiled. "Yeah... ok, I kinda want to know what it feels like too. Come here."
And with that the two wives were falling onto their bed and undressing. After a couple of minutes Gloria, harder than ever, found herself aimed directly at Sandy's dripping cavern. She'd been inside it last night but being a dildo felt so impersonal. This time she was flesh and blood and had a huge heap of jizz she wanted to unload inside of her friend. She could barely wait and sent sensations to Anna to make her feel the same.
"Ohhhhh" groaned Anna. "I need to be in you, now!"
Sandy's eyes went wide. She'd never seen Anna this impatient. She spread her legs even more and pulled her horny wife towards her. Both lesbians cried out in surprise at the strange sensations they were feeling. Gloria wanted to cry out but had no mouth to do so. All she could do was vibrate with pleasure as her friend's vagina massaged and rubbed her, all while her other friend began to thrust her in and out of the warm sleeve.
Anna fucked her wife hard and fast and, having no experience owning a penis, she came far too soon. She began to cum and shrieked at the unusual sensations happening to her.
Gloria got to experience them even more intensely. Her whole body shook, her balls tightened, and she squirted glob after glob of cum onto Sandy's cervix. Gloria marveled at the sight, loving how her cum filled the cave all around her.
